by A mysterious object near the Earth is the first known space rock made of what looks like a piece of the moon, a new study reveals.
It may, in fact, have split off the moon in an ancient collision with an asteroid.
The space rock, called Kamo'oalewa, was discovered in 2016.
It has been the target of study by Vishnu Reddy, an associate professor in cosmochemistry and planetary astronomy at the University of Arizona, and his PhD student Benjamin Sharkey.
